Historically timing chains were considered to be longer-lasting and more reliable than timing belts, although this is not necessarily the case on more modern engines.

Timing belts have improved in construction and durability over time, and historically a cambelt change was required as frequently as every 60,000 miles, today many cars have belts that the manufacturers state are good for more than 150,000 miles or ten years. Some manufactures even say that the belt is good for the life of the car, although the term ‘life’ in this context is arguably a little misleading.

If there is an issue with this timing at the very least you will experience poor engine running. Should the chain or belt deteriorate to the point where it fails, vital engine components can go completely out of sync and can even result in valves making contact with the top of the pistons.

If you are buying an older car and you plan to keep it for several years, you may wish to consider choosing one with a timing belt. Because engines with timing belts usually have a scheduled time for replacement, you can budget in advance for it and plan for when you will have the work carried out. Generally it is also a cheaper process, although this does depend on the particular car.

However, like any component, a timing chain is susceptible to wear and stretching over time, albeit over a longer period than a typical timing belt. It is also still capable of being neglected by poor servicing - adequate lubrication is essential for it to function correctly, so neglecting oil changes can cause problems.

Conversely, timing chains generally do not have a scheduled replacement point, but a car of advanced mileage may well require it and it is a matter of the condition of the individual car as to when this work may be required, if at all. It also tends to be a more expensive process than changing a belt.

In simple terms, the timing belt or chain controls the rotation of the camshaft, which in turn controls the opening and closing of the valves in the cylinder head. For your car’s engine to work optimally, the opening and closing of the valves needs to be precisely timed.

Oil leaks, poor performance, unusual noises from the engine, excessive smoke and overheating can all be warning signs of a work timing belt or timing chain, so if you are experiencing any of these problems it is important to have them checked out.

Long term reliability is a key factor for many car buyers so knowing exactly what's under your cars bonnet when it comes to maintenance is crucial. And the most critical part is the cambelt or timing chain.

On a basic level, a chain is a more sturdy component than a belt made of reinforced rubber, as well as having gaps for the timing sprocket’s teeth to fit into as a natural part of their design.

This can have catastrophic consequences. A broken belt or chain can also get caught up in other rotating engine components, causing yet more damage. This is why the condition and maintenance of your timing belt or chain is crucial.

Just as with the proverbial piece of string, the cost of a timing belt change varies considerably between manufacturers, specific engines, and where you have the work carried out.

Our guide will explain the difference between a cambelt and a timing chain and crucially show which cars have a cambelt and which are fitted with a timing chain.

As with most things, main dealers will charge more than independent garages, but a timing belt change can cost as little as £350, all the way up to £1000 or more. In most instances we would also recommend having the water pump changed at the same time, as the required access is usually similar and it reduces labour costs.

Timing belts and timing chains have their inherent advantages and disadvantages, so one is not clearly better than the other.

In most situations a visual inspection of a timing belt or timing chain will reveal little about its condition - unless it is very close to the point of failure. However, there are some other signs that may indicate the part is worn as it affects how the engine runs.

However, the age of car you are buying and how long you intend to keep it may influence your choices. If you are buying new then it should not be a concern assuming you are planning to stick to the recommended service intervals - or even more frequent than that.

There is a further complication thanks to ‘wet belt’ arrangements, where rather than operating as a dry belt, some engines run the timing belt within the engine oil. The advantage of this arrangement is better efficiency and reduced emissions, but the downside is that they are more susceptible to poor maintenance than dry belts.
